Basement Floor Void Fill

Problem:

A homeowner preparing to repair their sewer line discovered extensive voids under the slab floor of their home. The voids affected an approximately 500 square foot area, and were up to 9 inches deep. The customer was concerned that the floor would start to settle since it was only supported around the edges.

Concrete Jack surveyed the floor elevations and determined that the floor had not started to settle.

Solution:

Polyurethane grouting to fill the voids below the floor to reestablish structural integrity.

Result:

Concrete Jack foam jacking crew filled 14 cubic yards worth of voids under the floor using a specifically-formulated low heat void filling foam. It is important to use low heat foams when filling large voids. Lifting foams are not formulated for filling large voids.
